We took one of the Wildflower Center's Moonlight Tours of the gardens--this included the woodland trail and the arboretum (which I think is the same as the restoration/research trail also documented on this site).

The arboretum showed up best by full moon, with the prairie looking bright and silvery in the moonlight, and the trees as moody sporadic silhouettes.

Overall, there were rather fewer night-specific features than I had hoped, though it was a pleasant change to experience the center when it's mostly empty and not so hot.
